UHW-West"s leadership had refused to support the transfer of 65,000 homecare and nursing home workers into a different SEIU local union. The local had also been critical of deals struck by SEIU that prohibited nursing home employees from reporting safety concerns to authorities. After a brief standoff, SEIU International President Andy Stern placed UHW-West in trusteeship, removing its leaders and appointing two senior SEIU staff members to run the local.
The ousted leaders, together with other disgruntled members, announced the formation of NUHW just days later.
SEIU filed a federal lawsuit against NUHW and several former SEIU-UHW staff members in 2009, alleging they breached their fiduciary duty for opposing SEIU"s efforts to impose a trusteeship and for working to build a rival union while still employed by SEIU. On April 9, 2010, a jury awarded a total of $737,850 in damages to SEIU. In 1969, Rosselli worked with Dorothy Day of the Catholic Worker group, and later spent two years in the Peace Corps.
